Demand/Resale
Value***
$$$$$ $$$ $$$ $$ $ $$
*Data shown here may not be accurate and is based on equipment seen in the secondary market. See manufacturers for exact data
**Similar devices are manufactured by vendors other than the linear accelerator manufacturer
***Five $$$$$ indicate that the resale demand for like systems is high, and used equipment will therefore command a higher price
Few dollar signs indicate that the resale demand is lower, and prices for used equipment is lower. One $ indicates very little, if any, value currently exists.
